Compliance steps

1
Ensure the bill of entry includes all mandatory additional qualifiers for Chapter 28 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. These qualifiers became mandatory with effect from 15 October 2023 and non-compliance renders the import declaration deficient at assessment.

2
Verify that the exporter's commercial invoice and packing list are aligned with the qualifier particulars entered in the import declaration. Mismatches between the declared qualifiers and the accompanying documents are grounds for customs examination and potential detention of the consignment.

A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 28 mandatory qualifiers, treating them as optional supplementary information rather than a condition of assessment. CBIC Circular 23/2023-Cus made these qualifiers compulsory from 15 October 2023; a declaration filed without compliant qualifier entries is subject to customs examination, hold, and demurrage accumulation until the deficiency is rectified.

Frequently asked

Does HSN 2816 40 00 require BIS certification?

No, no BIS Quality Control Order covers oxides, hydroxides and peroxides of strontium or barium. Import compliance for this tariff line is governed by the Central Board of Indirect Taxes and Customs under CBIC Circular 23/2023-Cus, which mandates Chapter 28 additional qualifiers in every import declaration.

Which specific qualifiers are required at the bill of entry for Chapter 28 commodities?

The mandatory qualifiers are set out in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30 September 2023, effective 15 October 2023; importers should refer to the full circular text to determine the specific fields applicable to their consignment.

Does the Chapter 28 qualifier requirement apply to all forms of strontium and barium compounds under this heading?

Yes. CBIC Circular 23/2023-Cus applies to all commodities under Chapter 28 without a carve-out for specific sub-products, so all forms of strontium and barium oxides, hydroxides and peroxides classifiable under HSN 2816 40 00 are within scope.
